The United States Supreme Court overturned the death penalty judgment Tuesday of an Oklahoma man convicted of a 2010 triple murder. Justices ruled the victim impact statement where family of the deceased said the death sentence was appropriate should not have been admitted.

Shaun Bosse was convicted in 2012 of three first-degree murder charges in the killings of his girlfriend and her two children.

Gov. Mary Fallin and Department of Corrections Interim Director Joe Allbaugh both released statements acknowledging the 12-member panel of the multicounty grand jury and the process of reviewing capital punishment procedures.

“It is imperative that Oklahoma be able to manage the execution process properly,” Fallin said in a statement Thursday.

A dozen Oklahoma attorneys and business leaders are donating their time to independently review Oklahoma’s capital punishment practices. Former Oklahoma Gov. Brad Henry is co-chairing the Oklahoma Death Penalty Review Commission.

“Oklahoma has an opportunity to lead the nation by being the first state to conduct extensive research on its entire death penalty process, beginning with an arrest that could lead to an execution,” Henry said in a press release.

A third high-ranking official associated with Oklahoma’s death penalty protocols stepped down Thursday. Governor Mary Fallin's legal counsel Steve Mullins announced his resignation after working for the governor since February 2012.

Oklahoma’s Department of Corrections Director Robert Patton announced his resignation earlier this month, and he’ll begin taking leave at the end of this week. Under his watch, the state gained national attention for multiple execution snafus. But Patton’s tenure goes beyond the death chamber.

The last execution scheduled in the U.S. for the year is set for Tuesday in Georgia. But capital punishment has gown rare in America, to the point of near extinction.

Even though polls show that 60 percent of the public still supports the death penalty, and even though the Supreme Court has repeatedly upheld it as constitutional, the number of executions this year so far is almost the same as the number of fatalities from lightning strikes — 27 executions versus 26 deaths by lightning.

America's death penalty is under scrutiny after a series of botched executions, drug mix-ups and difficulty acquiring lethal injection drugs. Just last month, President Obama called certain parts of capital punishment "deeply troubling."

Some say long waits and repeated last-minute delays are tantamount to torture.

Attorney General Scott Pruitt agreed Friday to indefinitely stay the scheduled executions of three death row inmates until the completion of a grand jury investigation into the Department of Correction’s lethal injection process. The agreement was reached between the attorneys representing inmates on Oklahoma’s death row in the case, Glossip v. Gross.

The Oklahoma Court of Criminal Appeals has granted the state's request to indefinitely stay three scheduled executions, citing the mix-up over lethal injection drugs that occurred just minutes before condemned inmate Richard Glossip was supposed to be put to death.

"Having fully considered the State's request, we find for good cuae shown, the executions set for October 7, 2015 - Benjamin Robert Cole; October 28, 2015 - John Marion Grant; and November 6, 2015 - Richard Euguene Glossip are indefinitely stayed," the court wrote.

The Oklahoma Court of Criminal Appeals denied death row inmate Richard Glossip’s request for a hearing on evidence his attorneys say casts doubts on his guilt, paving the way for his execution Wednesday afternoon.

Death row inmate Richard Glossip is questioning whether a court order last week delaying his execution for two weeks violates state law.

Glossip is set to die for the 1997 murder of Barry Van Treese, who was beaten to death in the Oklahoma City motel he owned. Justin Sneed, the maintenance man at the Best Budget Inn, said Glossip paid him to kill their boss.

The Oklahoma Court of Criminal Appeals granted a last-minute stay of execution Wednesday to Oklahoma death row inmate Richard Glossip, a little over three hours before he was set to die by lethal injection.

Standing outside the Oklahoma State Penitentiary, anti-death penalty advocate Sister Helen Prejean said the two extra weeks will give Richard Glossip’s lawyers time to present what they say is new evidence that will clear his name.
